As shown in fig. 1, the temperature adjusting system includes a heat collector installed outdoors, a heat-conducting oil tank connected to the heat collector through a first oil suction pump, a heat exchanger connected to the heat-conducting oil tank through a second oil suction pump, a water storage tank connected to the heat exchanger through a first water suction pump, and a second water suction pump connected to a water outlet of the water storage tank.
In one embodiment of the application, under the condition that water in a water storage tank needs to be heated, a first oil suction pump is started to input heat conduction oil in a heat conduction oil tank to a heat collector, the heat collector is placed outdoors, and the heat conduction oil is heated through solar illumination.

Fig. 2 is a flowchart of a temperature adjustment method for hotel water according to an embodiment of the present application. As shown in fig. 2, the temperature adjusting method for hotel water includes the following steps:
s201, the server receives a room reservation request of the user, and calculates the time of the user reaching the hotel as soon as possible according to the room reservation request and the hotel position.
In one embodiment of the application, the server determines the current location of the user, a first time for sending the request, and a second time for the scheduled arrival according to the room scheduling request. And obtaining a plurality of paths which the user may go to according to the current position of the user and the position of the hotel, and respectively determining the weather conditions respectively corresponding to the paths. And estimating the actual time of the user arriving at the hotel according to the multiple paths, the weather conditions and the first time corresponding to the paths respectively, and obtaining the fastest arrival time of the user corresponding to each of the multiple paths. And determining the time closest to the second time from the fastest arrival time of the user, and taking the closest time as the most probable arrival time of the user.
Specifically, the server receives a room reservation request sent by a user, wherein the reservation request comprises the current position of the user, the time when the user sends the reservation request, and the time when the user reserves to reach a hotel. And the server plans the path of the user from the current position to the hotel according to the acquired information. And counting the weather conditions corresponding to each path respectively, wherein the time lengths of the paths of the same path under different weather conditions are different. For example, in rainy days, roads may have a certain congestion, which increases the time period. The accuracy of the time length of arriving at the hotel corresponding to each path is improved by acquiring the weather condition. The time of arrival at the hotel of the user can be calculated from the time of arrival at the hotel and the first time of the transmitted reservation request of the user.
Specifically, the estimated fastest arrival time corresponding to each of the multiple paths is compared with a second time which is sent by the user and is scheduled to arrive, and the time closest to the second time is determined. At this time, the path to which the user goes may be estimated, and the time for heating with water may be calculated based on the time closest to the second time.
It should be noted that, if the server receives the user room reservation information, it is displayed that the first time that the user has checked the sending request is not the departure time option, at this time, the user may be reminded to resend the departure time when actually departing.
For example, when a user is currently at an airport in a certain city, the server may obtain the position of the airport, plan a path from the airport to a hotel, and plan a plurality of different paths, where the time duration corresponding to each path is different. If the weather condition corresponding to each obtained current planned path is sunny and the time of receiving the request sent by the user is 9 am, the calculated time duration corresponding to each path is 1 hour, 10 minutes and 1 hour, 30 minutes, at this time, different paths taken by the user can be estimated, and the time of arriving at the hotel is 10 am, 10 am and 30 am respectively. And the received user scheduled arrival time is 10: 40 points, and at this time, 10: 30 points can be taken as the most probable arrival time of the user.
In an embodiment of the application, when a difference between a fastest arrival time of a user and a received second time is greater than a first preset difference, the received second time is determined to be an error time. And sequencing the fastest reaching times of the users according to the time sequence, and sequentially calculating the time difference between the fastest reaching times of two adjacent users according to the sequencing sequence. And determining the time difference value smaller than the second preset difference value, wherein the time difference value corresponds to the user to reach the time set fastest respectively. And determining the earliest time in the user fastest arrival time set, and taking the earliest time as the most probable arrival time of the user. And calculating the heating time of the water temperature according to the most probable arrival time.
Specifically, if the difference between the calculated fastest arrival time of the user and the second time sent by the user is large, it is indicated that the scheduled arrival time sent by the user is an error time, and the user may forget to modify the scheduled arrival time when sending the room request.
Specifically, the server estimates a user's likely arrival time based on the calculated multiple fastest arrival times. For example, the currently calculated fastest arrival time of the user is sorted into 9: 10, 9: 30, 9: 40 and 12 in sequence, at this time, the difference between two adjacent arrival times can be calculated to be 20 minutes, 10 minutes and 2 hours and 20 minutes respectively, at this time, it can be determined that the difference between the last arrival time and other arrival times is large, the time is removed, in the remaining time, the earliest arrival time 9: 10 is selected, and 9: 10 is taken as the most probable arrival time of the user. From this most likely time of arrival, the time at which the water temperature starts to heat is calculated.
S202, acquiring the temperature of the heat collector and the water temperature in the hotel room through the temperature sensor.
In an embodiment of the present application, the temperature of the current heat collector is obtained through the temperature sensor, and the heat collector is used for heating the heat conduction oil, so that the heat conduction oil can reach the temperature required by the heating water temperature after the heat collector reaches the corresponding temperature. The temperature sensor is used for acquiring the water temperature in a hotel room, if the water temperature is 65 degrees lower than a first preset temperature value, the water temperature needs to be heated, and if the water temperature reaches 65 degrees, the water temperature does not need to be heated.
Specifically, under the condition that the water temperature is 65 degrees lower than a first preset temperature value and the temperature of the heat collector is 55 degrees higher than a second preset temperature value, a first oil suction pump is started to convey heat conduction oil in a heat conduction oil tank to the heat collector to heat the heat conduction oil, and the heated heat conduction oil is conveyed to the heat exchanger. And starting the first water suction pump to convey water in the water storage tank to the heat exchanger, and conveying the heated water into the water storage tank after heating the conveyed water.
S203, the server calculates the time for starting heating the water temperature according to the time when the user most probably arrives at the hotel.
In one embodiment of the application, the liquid level height of a water storage tank corresponding to a room predetermined by a user is obtained. And under the condition that the liquid level height is smaller than the standard liquid level height value, controlling a third water suction pump to inject cold water into the water storage tank until the liquid level height is larger than or equal to the standard liquid level height value. And starting the first oil suction pump to input the heat conduction oil in the heat conduction oil tank into the heat collector. The temperature and the current illumination intensity of heat conduction oil in the heat collector are obtained, and the heating of the heat conduction oil in the heat collector to the standard oil temperature and the required illumination time are determined according to the temperature and the illumination intensity of the heat conduction oil in the heat collector. The heating rate of the current heat exchanger is obtained, and the heating time length required for heating the water in the water storage tank to a first preset temperature value is determined according to the liquid level height and the water temperature in the water storage tank after cold water is injected. And determining the total time required by heating the water temperature according to the heating time and the illumination time. And obtaining the time for starting heating the water temperature according to the total time required by heating the water temperature and the time which can be reached.
Specifically, the liquid level height of the water storage tank corresponding to the room is obtained according to the room number preset by the user, when the liquid level of the water storage tank reaches the standard liquid level height value, water in the water storage tank is directly heated, and if the liquid level height does not reach the standard liquid level height value, cold water needs to be injected into the water storage tank.

For example, the heating time required for heating the water in the water tank to the first preset temperature value is calculated to be 40 minutes, and the whole heating process can be obtained to be 70 minutes. If the user most likely arrives at 11 o 'clock, then heating needs to begin at 9 o' clock 50.
It should be noted that the temperature value of the cold water injected into the water storage tank is less than the first preset temperature value. The lowest temperature of the heat conduction oil for heating the water is 55 degrees of a second preset temperature value, and when the water temperature needs to be heated to a temperature value higher than 55 degrees, the temperature of the heat conduction oil needs to be heated to a temperature higher than 55 degrees.

Or, if the calculated heat preservation time for the water temperature to be reduced to the minimum heat preservation temperature of 40 ℃ is short, that is, the water temperature needs to be reduced to 40 ℃, the electric heating device needs to be started to heat the water temperature.
